A decoded flac is bit for bit identical to the orginal wav file ripped
from the cd. Not waveform identical. Bit for bit identical. If you
don't believe me test it.

$ cdparanoia 1 foo.wav

$ flac foo.wav
options: -P 4096 -b 4608 -m -l 8 -q 0 -r 3,3
foo.wav: wrote 36873547 bytes, ratio=0.694

$ flac -d -o bar.wav foo.flac

$ md5sum foo.wav bar.wav
f46734c640ba0006e7d4fc6dc75dbf3c  foo.wav
f46734c640ba0006e7d4fc6dc75dbf3c  bar.wav

You can't get more identical then that.

(bonus points to whoever can guess which CD I used. Here is a hint:
The artist is Canadian.)
